7-Day Pollen Forecast for Prague
Pollen Season in Prague
Prague's pollen season reflects the Bohemian Basin's varied landscape: deciduous forest on the surrounding hills, river meadows along the Vltava and Berounka, and agricultural land on the plateau. Alder along Prague's river banks starts the season in late February. Birch is the dominant tree allergen — Stromovka park, Divoká Šárka, and the forests of Prague's hill districts produce high counts in April. The Vltava valley can channel and concentrate pollen during morning inversions, producing especially high readings in the city centre. Grass pollen from Bohemian meadows and the Elbe basin peaks in May and June. Prague's compact historic centre means residents are rarely far from green spaces that contribute to urban pollen. Approximately 20% of Prague residents experience seasonal allergic rhinitis, and rates have been rising alongside birch woodland expansion.
- Vltava valley morning inversions can trap and concentrate birch pollen in the city centre in April — symptoms may be worse in Charles Bridge area mornings.
- Divoká Šárka and Prokopské údolí nature reserves have dense birch and hazel; avoid them on dry, sunny April afternoons.
- Check Czech Hydrometeorological Institute pollen bulletins — they provide regional Bohemia forecasts more granular than international models.
